"I think he's the best player in the country," said teammate Jon Diebler, who added 17 points. "The guy does everything."

Dallas Lauderdale had a career-high 14 points for Ohio State, which has won the last 30 times it has hosted the Wildcats, dating to 1977.

John Shurna had 22 points and Drew Crawford had 11 for Northwestern (13-5, 2-4), which played its third straight game against a ranked opponent. The Wildcats beat No. 6 Purdue 72-64 on Saturday, the highest-ranked team they had beaten in 31 years.

At one point in the second half, the Wildcats hit 8 of 10 shots from the field but cut only three points off what was a 23-point deficit at the break.

"They're playing as well as anyone," Northwestern coach Bill Carmody said of the Buckeyes, who are finding their groove after Turner missed 4 1/2 weeks with an injury that caused him to miss six games. He's been back for the past five.

The Wildcats hit nine of 23 3-pointers -- they're in the top 10 in the nation in shots made and attempted behind the arc -- but never had an answer inside against the more aggressive Buckeyes.

Carmody said the Wildcats had a bad day Monday in practice and that seemed to carry over into the game.

"From the get-go they jumped on us and we weren't even in the game," Carmody said. "They passed the ball really well, and they seemed to be hitting on all cylinders."
